Specificatiors Patent. Patterned Apr, 11 1), 1917.

Application filed August 21, 1913. Serial No. 786,048.

To aZZ whom it may concern:

Be it known that I, LUIGI SANTA, a subject of the King of Italy, residing at No. 21 Col-so Oporto, in the city of Turin, Italy, have invented a new and useful Improvement in Density Regulators for the Atomiz ing of Water Under Pressure and of Steam in Lead Chambers; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relatesto regulating devices for acid plants, and has for its ob ect to provide a device which will automatically regulate the action of the water atomizers in the generating chambers of the acid plant and thereby control the density of the resulting acid, whereby regular operat1on of the plant, and acid of a standard denslty are obtained.

To this end I provide an approximately balanced lever carrying at one end a cup into which the acid from the producing tank continuously flows. This lever is moved one way or the other as the densityand the specific gravity of the acid becomes too great or too small, and sets in operation a clockwork, opens or closes a controlling valve in the pipe conducting water to the atomlzers.

Another object is to provide a devicefor indicatinghow the apparatus is operatrng.

In the accompanying drawing, showing by way of example, an embodiment of the invention,

Figure 1 is aside elevation of the apparatus;

Fig. 2 is a vertical section throughthe clockwork,parts being shown in elevat1on;

Fig. 3 is a plan of the apparatus; Fig. l is an end view of the clockwork;

valve.

The apparatus comprises (1) An ordinary clock work mounted between two connected metallic plates;

(2) a lever Z provided with an adjustable counterweight at one end and fork shaped at the other end in which swings a glass cup 6 in a kind of a suspended stirrup; and

(3) an apparatus for testing the passlng of the water, which consists of two glass tubes mounted between two metallic plates the upper one of which is connected with the atomizers by means of tubes and the lower with the automatic valve o.

The clock work is set in motion by an ordinary spiral spring located in a barrel a, the toothed rim of which engages the driving wheel 74 which in turn drives the toothed wheel 0, which is rigidly fixed on the same shaft. The toothed wheel r oommunicates its movement to the toothed shaft 7* and the latter to the toothed wheel 9 Finally the toothed shaft r drives the wheel r and the ratchet wheel 4". On the shaft of the ratchet wheel r 'there is mounted a small disk 0 having studs protruding from both its faces, which serve as stops for the levers Z, Z These levers carry respectively projections ti and (Z each 'of which rests upon a smooth crown at the side of its respective wheel 7, r and each crown having therein a recess 1, W in which said projections respectively engage.

Both crowns, with relation to the cams d, 03 are so disposed that when one recess is engaged by its respective cam, the other recess is diametrically opposite the other This valve opens or shuts off the water supply which is fed in the direction of the arrow through the pipe 7 and is led into the atomizers, which are mounted in the lead chambers and as their name indicates distribute either the water or steam in the shape .of a very fine spray or mist. Fig. 4? is a section through the controlling On the shaft carrying the disk 0 is mounted a vane wheel it freely rotatable thereon U which is provided with adjustable vanes in order to exercise more or less resistance to the air. This vane wheel has two blade springs which engage in the teeth of a disk p rigidly mounted on the shaft, whereby the vane wheel may revolve forwardly relative to the shaft but not backwardly.

' The apparatus operates as follows The sulfurous acid gases coming from the Glovers towers pass into the chambers; by the chemical action of the steam or the atomized water, the gases are condensed and part of these aqueous gases stick to the Walls of the chamber, collect in the pipes and drip out of them through a small tube 0 into the Thus the driving mechanism can be set in operation by the action of the spiral spring, which it could not do before.

By reason of the relation of the wheels to each other the toothed wheel r makes one half revolution at the same time as wheel 1' then the eccentric 6 assumes the position shown in Fig. 4 thereby swinging the lever Z and thus opening the valve 1) against the action of the spring 0 The opening of the valve 1) admits water to the atomizer; as a consequence thereof the chemical combination of the gases diminishes the density of the produced acid. The wheel 1 accomplishes only one'half revolution because by the movement of the wheel 7" the wheel r brings the recess in its crown' under the tooth 6Z which before was resting on that crown, which tooth then engages in the 'notch, while the lever Z swinging down strikes against the stud of the disk 0 and stops the motion of the latter. The vane wheel being loose on the shaft, may still accomplish some revolutions on account of inertia and serves as regulator during that movement. When by an excessivefeeding '40 of water into the chambers,'the density of the acid decreases, its weight in the cup is nots'ufiicient to overcome the weight of the counterweight w and the lever Z swings upward causing the crank arm m to move the lever Z thereby disengaging the tooth d and the stud of the disk 0 so that the rotary motion in the direction of the arrow will be resumed until the tooth d again engages with the recess in the crown of the wheel r and stops the movement of the disk 0. This happensthe moment that the turning of the wheel o causes the eccentric e to assume" such a position that the lever Z moves to permit the valve '1) to close under the action of the spring a Thus the oscillating movement 'occursat every change of density, thereby regulating uniformly the production of acids of a desired and standard density.

If it be desired to obtain a predetermined degree of density theposition of suspension of the cup I) may be changed, to which efi'ect the forked end of the lever Z is provided with notches into any opposite pair of which the bracket bearing of the cup will fit. The distance between the cup and the swinging section in Fig. 1.

The cup is thus constructed in order that the acid may run out at all degrees of den sity, whereas if the acid were allowed to run over the edge thereof the lower layers of liquid always remain stagnant.

The water for the atomizers enters through the tube 7 and flows in the direction of the arrows (Fig. 1) so that it passes into the cylinders t through a strangulated part at the bottom thereof which latter serves as a seat for the balls at which by the incoming flow are caused to vibrate and turn, thereby proving that the water flows properly through the apparatus and that the latter works as it should.

The controlling apparatus comprising the two tubes may be located at any desired place depending upon where it can be watched in the most convenient way by the operators. Any number of such apparatus for each chamber may be used.

The apparatus has the following advantages:

(1) Besides its simplicity because it comprises only a few wheels and levers, the main advantage is the automatic operation thereof caused directly by the greater or less density of the sulfurous acid and consequently of its weight.

(2) The apparatus may be used for distilling alcohol.

(3) It can moreover be used for atomizing solutions of nitrosulfurous acid or water only; 7
